Title:
OPTICAL DEFOCUS LENS AND METHOD FOR IMPLEMENTING OPTICAL DEFOCUS
Document Type and Number:
WIPO Patent Application WO/2022/241753
Kind Code:
A1
Abstract:
An optical defocus lens. The optical defocus lens comprises: a first lens layer and at least one liquid crystal lens layer; the first lens layer is a concave lens, a convex lens, or a flat lens; the refractive index of liquid crystal molecules in each of the at least one liquid crystal lens layer is controlled by an electric field, and each liquid crystal lens layer is used for converging or diverging polarized light incident in a specific direction of each liquid crystal lens layer to form a focal point, wherein a first liquid crystal lens layer is used for converging or diverging polarized light in a first direction to form a first focal point, the first lens layer or a second liquid crystal lens layer is used for converging or diverging polarized light in a second direction to form a second focal point. The liquid crystal lens layers are controlled by the electric field to form focal points, and thus optical defocus can be implemented while shortening the processing cycle and reducing production costs.
